Welcome to the small circle of individuals who,
if we are to be absolutely precise, demand slightly more
of a watch than absolute precision. Appreciation of a
watch is more than mere appreciation of the correct time.
It is enthusiasm for an ingenious idea. For the interplay
between precision and imagination. Between time and
timelessness. Between boundaries and infinity. Between
laws to which the entire world is subject, and taste, which
cannot be dictated to anyone. That is why, since 1868, we
have been devoting rather more of our time to watches
that must not only run with absolute precision but which
also, with every passing second, exert a fascination with
the great achievements of master craftsmanship: a fasci-
nation with new inventions of a technical, material or for-
mal nature, even if they are concealed in minute details
that are perhaps not even visible. You are now the owner
of a beautiful new example of this IWC tradition. We
would like to congratulate you on your choice and send
you our best wishes for the time you will spend with your
watch, which perhaps cannot be described with any
greater accuracy than it is here.
IWC Management

The technical refinements
of the Aquatimer Chronograph
Your IWC watch shows you the time in hours, minutes
and seconds, together with the date. You can use
the integrated chronograph to measure any period in
seconds, minutes and hours. Stop times can be added
together. Dive time is read off on the external rotating
bezel, which for safety reasons can only be turned
anticlockwise. The mechanical movement with auto-
matic winding has 40 jewels (synthetic rubies) and
a power reserve of approximately 68 hours when fully
wound. Your Aquatimer Chronograph is shockproof,
water-resistant 12 bar and protected by sapphire glass
of hardness grade 9 on the Mohs’ scale. To ensure that
this extraordinary watch continues to perform faultlessly
in the future, it is essential to observe a few important
operating instructions.

Normal position
This watch has a screw-in crown. Screwing the crown
in to its normal position (X) prevents inadvertent adjust-
ment of the time or date and acts as a double seal
against ingress of water into the case. To release the
crown, unscrew it by turning it to the left, where it auto-
matically assumes position 0, the winding position.
By depressing the crown in position X and turning it to
the right at the same time, it is screwed down firmly
again and secured.

Winding position
With the crown in the winding position (0), you can also
wind the automatic movement by hand. A few revolutions
of the crown are enough to start the movement. How-
ever, it is better to wind the movement fully by turning the
crown through about 40 revolutions. This will ensure
maximum accuracy and a power reserve of about
68 hours, even if you are not wearing your watch.
Date setting
If a month has fewer than 31 days, you will need to set
the date manually to the first day of the following month.
Pull the crown out to position 1. You can now set the date
by turning the crown to the right (rapid advance). You
should not use the rapid advance function between 8 pm
and 2 am because the movement automatically ad-
vances the date during this period.

Time setting
Pull the crown out to position 2. This will stop the move-
ment. To set the time accurately to the second, it is best
to stop the movement as the seconds hand reaches 60.
Now move the minute hand a few minutes beyond the
time to which you wish to set the watch. Then position
the minute hand by moving it gently backwards until it is
exactly above the correct minute stroke. This ensures
that the minute hand begins to move immediately when
you restart the movement. To start the seconds hand,
push in the crown to position 0. When setting the time,
please be aware of the date change, which always takes
place at 12 midnight. If this change has already taken
place at 12 noon, you must move the hands forward by
12 hours.
Setting your watch correctly
To set your watch correctly, proceed as follows:
• Release the crown by turning it to the left.
• Wind the movement until it is fully wound (about
40 revolutions of the crown).
• Pull the crown out to position 1.
• Turn the crown to the right to advance the date display
a day at a time. Set the display to yesterday’s date.
